Restrictions
The interrupt routine is treated as a normal subroutine. In other words, to be able to execute
interrupt routines, at least one subroutine level must be free. (16 program levels are
available, plus two levels that are reserved for the ASUB interrupt programs.)
The interrupt routine is started only during an edge change of the interrupt signal from 0 to 1.
If the interrupt signal remains permanently on 1, then the interrupt program is not restarted
any more.
